1) Sulfide indole motility test (although generally I would prefer a TCC for motility only)
2) Tests for bacterial motility/indole production (tryptophanase)/reduction of sulfate to hydrogen sulfide (cysteine desulfurase)
3) A: H2S-, indole+, motile = E Coli; B: H2S-, indole-, nonmotile = SA (otherwise known as Brownian motility); C: H2S+, indole-, motile = Salmonella; D: H2S-, indole-, motile = Enterobacter; E: H2S+, indole+, motile = Proteus

CI is a phenomenon that results in sperm and eggs that cannot form viable offspring and it is believed that unidirectional CI cannot promote speciation. First introduction to Wolbachia :D Some Q's from my test..

1. What does Phenol destroy in controlling microbial growth?
2. What is the lowest temperature that kills all microbes in liquid suspension for 10 minutes?

and a nice scenario xD

A high profile politician comes into the Emergency Room. He says the political turmoil is affecting his body, as he runs a high fever with headaches and a bad cough, but you do not believe the symptoms are from stress. He started developing symptoms after his wife bought him a fancy raccoon fur coat for his birthday.
3. What is the genus of the disease contracted?
4. What type of the disease did he contract?
5. What was the vector, where did the causative agent come from?
6. What treatment should be used for the politician?
7. What increases cAMP, a second messenger device?
8. Resistance to treatment in this microbial agent can be transferred through what
extracellular structure?

1. Phenol deactivates enyzme systems and disrupts the cell wall
2. Thermal death point
3. Bacillus
4. Bacterial (anthrax), inhalation
5. Raccoon/spores from soil, probably
6. Penicillin G
7. Edema factor (forms calmodulin-dependent adenylyl cyclase; thanks AP Bio!)
8. Plasmids encoding beta-lactamase?
(I have no idea if I answered correctly, because anthrax generally shows up in herbivores, but the only other cAMP-inducing bacteria is cholera. Respiratory anthrax sometimes presents with cold/flu like symptoms, so this is my best guess.)
1. Which vaccine was implicated in causing the disease it was trying to prevent, and where has this most recently occurred?
Image
2. What does this image represent? What is a PFU?

In regards to your question 1. Any Live Attenuated Vaccines can cause them, rarely, if secondary mutation occurs, and it happened recently in (not sure) an oral polio vaccine.
2. This image represents the growth curve of a bacteriophage, PFU = plague forming unit
In regards to my question: 5. i was thinking raccoon fur but that's fine
8. I was thinking sex pili xD very awesomeee job i thought those were pretty hard
